I was just looking up Col Henry M Carr on the internet. He was the Col of the 58th Indiana, the unit my great uncle, Capt Walter Bruce Carr was in. I am very curious about him since they share the same last name. I do not know if they are related, but I will now endeavor to find out.
In my search, I found that Jessie M Carr, daughter of Henry M Carr, died at age 7 and was buried in Kentucky. That link came up when I typed in Henry's name to search. It looks like a family plot in the pictures so my guess is that Henry is buried at the same place as his daughter.

Good luck in your search.
